A Florida man was arrested for trying to suffocate his pregnant girlfriend after they got into an argument over baby names, officials said.

Raul Lopez, 18, and his girlfriend’s dispute began at a Fort Myers Walmart, where Lopez allegedly said he wanted their unborn baby boy to be named after him, according to WBBH-TV.

But Lopez’s girlfriend reportedly had another name in mind, and the couple continued to fight about it until they got to the expectant mom’s home, where she locked herself in a room to avoid the increasingly heated confrontation, authorities said.

Lopez was charged with aggravated battery on a pregnant woman and domestic battery by strangulation. He has been released from jail and is scheduled for a court appearance on July 10, online records show.
